Description

Technical Field

[0001] The utility model relates to the technical field of anti-clogging water pumps, and more specifically, to an anti-clogging water pump. Background Art

[0002] In the existing technology, anti-clogging water pumps face some challenges, especially in terms of cleaning of the filter, cumbersome connection methods and sacrifice of connection sealing performance.

[0003] Firstly, water pumps in the prior art usually have a simple filter at the input end to block foreign matter. Although this design can prevent foreign matter from entering the water pump and causing blockage, it cannot clean up foreign matter on the outside of the filter in time. This means that although the water pump itself may not be blocked immediately, the pipeline system may still be blocked due to the accumulation of foreign matter on the outside of the filter. This problem will lead to reduced efficiency of the water pump and pipeline system, and may even require frequent maintenance and cleaning, increasing operating costs and inconvenience.

[0004] Secondly, the water pump in the prior art needs to be connected to the pipeline when in use. However, this connection usually adopts bolts and nuts. This process is time-consuming and laborious. The disassembly and assembly of bolts and nuts not only requires special tools, but also requires precise alignment and tightening during operation to ensure the stability of the connection. This cumbersome operation not only increases the time for installation and maintenance of the water pump, but may also cause loose connection due to improper operation, affecting the performance and life of the water pump.

[0005] In addition, although there are some structural designs in the prior art that can achieve quick connection and release of pipes, these designs often sacrifice the sealing performance of the connection. Quick connectors may improve the connection speed, but due to the lack of sufficient sealing mechanism, they may leak at the connection. Such leakage will not only lead to waste of water resources, but may also pollute the environment, especially when transporting chemicals or harmful liquids. Therefore, this design that sacrifices sealing performance improves connection efficiency while also bringing potential environmental and safety risks. Utility Model Content
